Compress Image to Exact KB Size (20KB, 50KB, 100KB)
Compress JPG, PNG, and WEBP images to exact target file sizes in KB (Under 20KB, 50KB, 100KB, 200KB, 500KB) for portal uploads.
Target File Size Image Compression: Exactly Hit 20KB, 50KB, or 100KB Limits
Many online job application portals and competitive exam forms strictly restrict upload file sizes to under 20KB, 50KB, or 100KB. Attempting to manually balance compression quality sliders is time-consuming. AuraToolkit360 automatically computes optimal quantization tables to meet your exact target size.
How Binary Search Compression Works
Our client-side algorithm uses a binary search routine across JPEG quality factors (from 0.05 to 0.95), measuring the generated buffer size in memory until it achieves the maximum possible visual clarity strictly within your specified kilobyte cap.
Frequently Asked Questions (FAQ)
β Why was my image rejected by an exam portal?
Portals often enforce both dimension limits (e.g. 200x230 px) and file size limits (e.g. max 50KB). Ensure both criteria match the portal instructions.
